Abstract (en)
The process comprises: providing a layer system with a metallic substrate (4) and an outer ceramic layer, reducing a layer thickness (30-80 mu m) of the outer ceramic layer using a laser process and a smoothing process during the post-treatment step, where the laser machining comprises creating passage holes using a diffuser. The laser machining of the layer system is performed without masking the outer ceramic layer.
Abstract (de)
Durch die bewusste Verdickung der keramischen Schicht (7) vor deren Bearbeitung, ist es möglich, diese mit den Verunreinigungen (16) abzutragen.
